BTW, many cars may not have a specific sensor. The inlet air temperature

to drive a low temperature warning.

Do you know of one where this is actually the case?

Nope.

That sensor is only
interested in temperature change rather than absolute values.

It needs to know the absolute temperature for cold start enrichment.

As I said normally the coolant sensor for this. If you think about it that
tells the temperature of the actual engine which effects the mixture
requirements - not the air temp one which shouldn't really sense engine
temp at all. After all you don't need choke on a hot engine on a
cold day. ;-)
